To all whom it may concern:

Be it Known that l, YOSHIMASA Masozswa,

a snbj set or": the Mikado of lapan, anda resi dent of l irmona, in thecounty of Kings and State of Calii'ornia, have invented certain new anduseful improvements in Swinging Gates, of which the following is aspecification.

My invention relates to swinging gates and has for its objectthe-provision of a gate operating means comprising a gate mechanism,operated by the wheelsof vehicles appreaching the gate, to open the gateaway from the vehicles and to hold it in a latched position until thevehicle has oassed through the gate, when the latch may be released bythe wheels of the departing vehicle and the gate is returned to itsclosed position by a weight. A latch is alsoprovided for the gate in itsclosed position that'is operated by the gate swinging mechanism.

ltly invention will be described in detail hereinafter and illustratedin the accompanying drawings in which- Figure 1 is a front viewof thegate, showing the boxing containing the gate and latch operatingmechanism in section, Fig. 2, an

view of the gate with the boxing in section. Fig. 3, a top plan view ofthe operat ingmechanism, Fig. 1, a detail view of the latch leveroperating mechanism, and Fig. 5, a detail of gate latch operatingmechanismjlfig 6, a sectional view onthe line of Fig. 5, Fig. 7, a Viewof the latch postand latches, and Fig. 8, a detail View of one of thelatch levers for holding the gate an open position.

In the drawings similar reference characters indicate correspondingparts in all of the views.

1 indicates the hinge post and 2 the latch post between which is swungthe gate 3 secured to a vertical shaft- 4; journaled on post 1 andhaving its lower end resting in a socket 5 secured to the base 6 of ahousing; or boxing 7 for the operating mechanism.

8 indicates a dish secured to shaft 4 and having an upstanding flange 9thereon iormed with e-Qnotch 10,

11 indicates a lever fnlcrumed on shaft 4 and having one end mountedinnotch while its other end has ropes, chains or other flexible elements12 secured thereto that extend through branches 13 of housing 7 to toarms 1 1 of shafts 15 gonrnaled at a distance from the gate at eitherside thereof. Shafts 15 are formed with upwardly extending crankportions 16 that are positioned to he engaged the wheels of vehiclesapproaching or leaving the-gate 17 indicates springs secured to disk 8and engaging opposite sides of le 11 to hold it normally midway betweenthe sides of notch 10.

18 indicates latch rods slidably mounted on latch post 2 which havetheir upper ends bent and inclined downwardly as shown at 19 to receivea pin or projection 20 secured to and extending outwardly from the endof the gate. 18 are pivotally secured to levers 21 ful- The lower ends'Of latch rods crumed on. bar 22 secured to cars 23, said le- I vers andtheir support being mounted in housing 94: under gate 3.

25 indicates carved wings pivotally secured to a support 26, the freeends of levers 21 being loosely secured to said wingsand 27 indicatestriangular shaped plate secured to the end of lever 11 and positioned sothat two of its sides engage the wings 25 when the lever 11 is moved bythe crank shafts 15 as hereinbefore stated, it being understood thatwhen the shaft 15 at one or the other side of the gate is rotated by anapproaching vehicle, the first efiect is to swing the lever 11 so thatthe end of lever 21 secured to the latch rod 18 atthe farther side ofthegate from the vehicle is raised by the triangular plate 27 engagingwings 25, then when the lever 11 engages the side of notch 10 the disk 8and shaftis rotated carrying with it gate 3.

28 indicates counter balance weights mounted .on levers fllthat tend tohold the latch rods 18 in their raised position to en gage pin 20.

29 indicates levers journaled on the inner sides of top plates 30 orbranch housings 13 that have upwardly extending portions .31 that extendthrough openings 82 in the top plates and formed with downwardly in-(lined ends 33 to engage the bottom of gate 3 when swung open, the otherends of the levers having; plates 34 thereon to engage. arms 14 of.shafts 15 .when rocked by the vehicle passing over the crank 16 of theshaft after passing through the gate. 35 indicates a counter balanceweight-on each lever 29 to hold the upwardly extending end 31 inposition to engage the gate when swung open,

36 indicates a weight connected to the.

disk 8 by means of a ropeor chain 37 mounted on sheave 38 and extendingthrough tubular guide 39"that operates to closefthe gate whenthe end 31of either lever'29 is released therefrom.

When the gate is opened, as heretofore described, by the approachingvehicle, passing overcrank 16 of shaft 15, it swings the gate 3 awayfrom the approaching vehicle and-into engagement with the end 31 oflever 29, the inclined end 33 of the lever by engaging the gate causesthe end 31'to be depressedqso that the gate passes itand it operates asa latch to prevent the'gate from closing. .After the vehicle passesthrough gate. The weight 36 will then close the,

the wheels are driven over the crank 16 of shaft' 15 on the side of thegate opening. to which the gate has-swung so that the arm 14: is swunginto contact with the plate 34: on the end of the lever lifting it'andswinging the end 31 'out of engagement with the gate, the pin 2O on theend of the gate, by engaging the inclined ends 19 of the latch rodat thenear side'of the latch post 2, depressing the rod until the gate closes,when i the counterbalance weight 28 on the lever will return the latch'rod to its normal position' and the gate will beheld in a closedposition.

Having thus described my invention what I claim is tively secured to thelatch "40 shaft, a disk 1. Agate operating mechanism comprisshaft, thegate secured to the ing a vertical secured to the shaft, a lever mountedon the disk, latch rods suitably mounted to engage the gate, leversoperarods, curved wings. pivotally mounted and loosely engag-' 7 ing thelatch operating levers,

the first mentioned lever constructed to engage the wings aforesaid, andmechanism operated by the weight of a vehicle approaching the gate toswing thefirst mentioned lever.

"2. A gate operating mechanism comprising a vertical shaft, the gatesecured to the, shaft, a disk secured to the shaft, an up standingflange around said disk and having a notch therein, a lever mounted onthe disk seatedin thenotch, springs secured to the diska'nd engaging thelevers to normally hold it" from engagement with the sides of the notch,"latch rods suitably mounied to engage the gate, levers operativelysecured to the latch rods, "curved wings pivotally fioples of thispatent-may be obtained for five cents each, by adfiressing' the tanceeachside of the mounted and loosely engaging the latch operating levers,a triangular plate mounted on one end of the first mentioned lever andengaging the wings aforesaid, and means operated by the Weight ofavehicle approaching the gate to swing the first mentioned lever.

mg a vertical shaft, thev gate secured to the.

shaft, a disk secured'to'the shaft, an upstanding'flange around saiddisk and having a notch therein, a lever mounted on the disk and seatedin the notch, springs secured to the disk and engaging the lever tonormally hold it from engagement with the sides of the notch, latch rodssuitably mounted to engage the gate, levers operatively secured to thelatch rods, curved wings pivotally mounted and loosely engaging thelatch operating levers, a'triangular plate mounted on one end of thefirst mentioned lever and engaging the wings aforesaid, crank shafts 3.A gate operating mechanism comprisjournaled at a distance on each sideof the gate and adapted to be actuated by a vehicle approachingthe gate,arms on said shafts,

and flexible members connecting the first mentioned lever and said arms.

4. In combination with a swinging gate,

a lever fulcrumed at a distance each side of the gate, one end of eachlever extended upwardly to engage the gate when opened, the other end ofeach lever extended horizontally, crank shafts positioned to be engagedby a vehicle passing through the gate opening, and a swinging arm oneach shaft and positioned to engage the horizontal portion of theadjacent lever and move its upwardly. extending end from engaging thegate.

. 5. A of a vertical shaft, the gate operatively connected tosaidjlshaft, crank shafts at a disbe rocked by avehicle passing overthem, a disk secured to said vertical shaft, an upwardly extendingflange on said disk and having a notch therein, a-ievercon thedisk andmounted in said notch, and operative connections shafts.

In testimony whereof" I hereto afiix my gate and adapted to between saidlever and the crank gate operating mechanism consisting signature in thepresence of two witnesses.
